Trunk comparison: BMW iX1 vs VW Tiguan Allspace

Key Differences (highlighted: >10%)
The VW Tiguan Allspace offers a significantly longer cargo space with folded seats: +11 in (17%) more loading length than the BMW iX1. Likewise, the Tiguan leads in cargo space length with the first row of seats upright: +8.7 in (24%) longer usable length.
Conversely, the BMW iX1 has a significantly larger trunk with all seats upright: +16.9 in (91%) more length than the Tiguan. Additionally, the floor depth (distance from loading edge to trunk floor) in the BMW iX1 is +0.8 in (100%) greater than in the Tiguan.
Impact on Usability
These differences result in clearly different strengths in everyday use: The Tiguan Allspace is the better choice if you frequently transport long items or often drive with folded seats (e.g., furniture, long pipes, skis): the extra loading length with folded seats and with the first row upright allows longer cargo and more flexibility when loading.
The Tiguan also has a slightly wider loading opening (+2 in), which simplifies loading wider items (this difference is under 10% and thus less emphasized).
The BMW iX1 scores in everyday trunk use with all seats upright: significantly more usable loading area for luggage, shopping bags, or strollers.
The greater floor depth of the iX1 makes stacking easier and provides a bit more interior volume directly behind the loading edge. Also, the loading edge in the BMW is lower (the Tiguan’s is +2 in higher), which simplifies lifting heavy items into the iX1.
Other dimensions: trunk opening height and narrowest trunk width are the same in both models; the slightly larger opening width of the Tiguan (≈+2 in / 5%) and the ≈+2 in higher loading edge of the Tiguan exist but only marginally affect usability.
Conclusion — which choice fits which user?
- Those who frequently transport long or bulky items and need flexible loading lengths: VW Tiguan Allspace.
- Those who mostly drive with all seats occupied and need a lot of usable trunk space for luggage, shopping, or child gear (with easier loading due to lower loading edge): BMW iX1.
